空泡蝶鞍综合征的CT诊断及临床表现

CT Diagnosis and Clinical Feature of the Primary Empty Sella Syndrome

目的：提高对空泡蝶鞍综合征的CT诊断及临床表现的认识。材料与方法：回顾分析17例空泡蝶鞍综合征的临床与CT表现。结果：17例中有15例表现为内分泌症状，主要有停经泌乳、尿崩症等，另2例表现为视力障碍。常规轴位、冠状位CT扫描征象有：鞍内低密度、鞍上池模糊、三脑室下移、“漏斗征”、垂体蒂下移、后移，垂体受压变扁平，蝶鞍扩大等；脑地造影CT可见造影剂进入鞍内。结论：作者认为本症临床表现与致病因素及病变的严重程度有关，CT是较理想的诊断手段。横断面CT可作筛选，冠状面CT一般可明确诊断，疑难者可由脑池造影CT确诊。

Purpose:To improve the recognization of the CT diagnosis and clinical features of the primary empty sella syndrome,Materials and methods:CT and clinical features of 17 cases with the primary etnpty sella syndrome were retrospectively studied.Results:The main clinical features in 15 cases were of endocrine dysfunction,such as galactorrhea、oligo-amenorrhea、dia betes insipidus,and visual disturbances in 2 cases.CT findings by the cross or coronal section CT included:a low-density region within sella turcica,dimmishing of suprasella cistern,prolapsing of the third vertricle,the infundibulum sign,disposition of the pituitary stalk,flattening of the pi tuitary gland and enlarging of the sella turcica;the contrast agent was seen in the sella turcica by cisternography CT.Conclusion:It revealed a close relationship between the clinical features and the cause or severity of the disease.CT was one of the best methods for the diagnosis of the pri mary empty sella,for the diagnosing,the coronal section CT is a dependable method,and cis ternography CT can prove it
